Sameet Agarwal 2fd6f2a829 HBASE-13316 Reduce the downtime on planned moves of regions ... Summary: The current behavior of a region move shuts down a region and then starts is up in another regionserver. This causes increased latency and possibly timeouts till the new region's cache is fully warmed up. We can make a region move less disruptive by warming the cache in the destination region server before shutting dow the old region. See https://issues.apache.org/jira/browse/HBASE-13316 Test Plan: 1. Unit Tests 2. Added test for concurrent moves and warmups 3. Manually tested reads/writes happening with concurrent moves Subscribers: tedyu Differential Revision: https://reviews.facebook.net/D35967 Signed-off-by: Elliott Clark <eclark@apache.org>		2015-03-27 11:56:21 -07:00
